I'm doing a kind of cartoon rendering. I use a 1D texture to store shade values. It looks working fine unless the single texture coordinate is 1.0; then every thing is messy.
Shade values are random and changing as I move or resize the window. I'm rendering trinagles as smooth shaded and 1D textured.
I tried to pass the 1.0 texcoord in a similar program, not mine, and I got the same distrubing results.
Is it a driver problem? or is it a normal thing?
